8-Well Strip Frames, 12 Positions, High Impact Polystyrene (HIPS), Black — 290-8103-Z1N | 12/Bag

Technical Narrative

The Caplugs® Evergreen is a black High Impact Polystyrene (HIPS) 8-well strip frame with 12 strip positions — the reusable SBS format holder that converts individual 8-well strips into a fully-addressable 96-position microplate footprint compatible with standard plate washers, readers, and robotic liquid handlers. The strip frame format is the preferred configuration for partial-plate ELISA programs where running full 96-well plates wastes reagents and antibody-coated wells on small sample batches — load only the strips required for the day's run and return unused antibody-coated strips to cold storage, reducing per-sample reagent costs by 50–90% for low-throughput assay programs.

Black HIPS construction serves two functions: the high-contrast black frame minimizes optical well-to-well cross-talk in fluorescence strip assays, and HIPS's rubber-toughened matrix provides the autoclave compatibility (121°C) that standard PS strip frames lack — enabling sterilization between strip changes for contamination-sensitive cell-based strip assays. HIPS also withstands the mechanical forces of automated plate gripper arms without frame fracture, making it the preferred strip frame material for high-throughput automated screening environments where standard PS frames become brittle under repeated robotic handling.

At $25.99 per 12/Bag — $2.1652 per frame — the delivers reusable strip frame infrastructure at economics that support dedicated frame-per-assay workflows without single-use overhead.

Technical Specifications — Caplugs® Evergreen

Strip Frame Application Compatibility —

The 8-well strip frame holds 12 individual 8-well strips to create a full 96-position SBS-footprint format for strip-based workflows. Black HIPS minimizes optical cross-talk in fluorescence assays.

Confirm strip-to-frame fit with your specific 8-well strip brand before bulk purchase — strip flange dimensions vary slightly between manufacturers. HIPS frame is autoclave-compatible for decontamination between strip loads.

Chemical Resistance — High Impact Polystyrene (HIPS)

HIPS provides better solvent and impact resistance than standard PS — suitable for autoclave sterilization between strip changes.

Laboratory Applications

The strip frame serves clinical laboratory ELISA programs running partial-plate antibody-coated strip assays; research labs combining different 8-well strips in single multi-assay plate runs; PCR programs converting 8-strip tube strips to SBS format for automated plate handlers; drug discovery compound dilution programs requiring SBS format strip plates; and any laboratory using 8-well strips that requires SBS-footprint compatibility with automated washers, readers, or robotic handlers.

Frequently Asked Questions — Caplugs® Evergreen

What is the advantage of a strip frame format over a standard 96-well plate?

The strip frame allows modular plate loading — run only the strips you need rather than a full 96-well plate. For ELISA assays with antibody-coated strips, unused strips can be returned to cold storage, reducing per-sample coating reagent waste by up to 90% versus pre-coated full plates. The SBS-footprint frame maintains compatibility with automated washers, readers, and liquid handlers regardless of how many strips are loaded.

Are standard 8-well ELISA and PCR strips compatible with the ?

The is designed for standard 8-well strips with SBS-standard inter-strip spacing. Most major ELISA strip brands (Thermo Fisher Nunc, Greiner, Corning) and PCR 8-strip tubes in standard SBS-spacing format are compatible. Strip flange dimensions vary slightly between manufacturers — always validate strip-to-frame fit with a sample set before large-volume purchase.

Is the frame autoclave-compatible?

Yes. The is molded from High Impact Polystyrene (HIPS) which is autoclave-compatible at 121°C / 15 psi — unlike standard PS strip frames which warp or crack under autoclave conditions. HIPS is also compatible with UV decontamination cycles. Autoclave the empty frame — remove all strips before autoclaving.
